GridView数据导出到Word/Excel中

GridView控件是表格控件，可以显示数据、修改数据，但是GridView控件控件没有办法保存数据。那么为GridView控件寻找一种保存数据的方式就很重要了。在NET2.0中加强了数据绑定控件与Office软件的结合。使得GridView控件可以借助于Office文件来保存自己的信息。

      在开始写导出GridView控件中的数据代码之前，首先要把以下代码using System.IO添加到引用头文件里面。System.IO是使用Word等文件的命名空间。同时还要把using System.Data.SqlClient也添加进去。在名称为Button1对应的“Click”事件中写如下代码。

protected void Button1_Click(object sender, EventArgs e)

{

//声明一个字符串

        string sConnectionString;

        //连接数据库字符串，连接到XBMIS数据库，用户名是sa

        sConnectionString = " Data Source=.;Initial Catalog=XBMIS;User ID=sa; ";

        //创建SqlConnection数据库连接对象

        SqlConnection Conn = new SqlConnection(sConnectionString);

        //打开Conn

        Conn.Open();

        //sql语句把T_YongH表中的数据信息都取出来

        string commandString = "Select BianH AS 编号,ZhuCYHM AS 注册名,XingM AS 姓名,XingB AS 性别 From T_YongH";

        SqlDataAdapter dataAdapter = new SqlDataAdapter(commandString, Conn);

        ds_datatable ds = new ds_datatable();

        //填充数据集

        dataAdapter.Fill(ds, "YongH");

        DataTable dataTable1 = ds.Tables["YongH"];

       //清除客户端当前显示

        Response.Clear();

        Response.Buffer = true;

        //输出类型为Word

        Response.ContentType = "application/vnd.ms-word";
                //输出类型为Excel
               Response.ContentType = "application/vnd.ms-excel";

        Response.ContentEncoding = System.Text.Encoding.UTF8;

       //设置显示的字和内容要存的形式

        Response.Charset = "Word文档";

        this.EnableViewState = false;

        StringWriter oStringWriter = new StringWriter();

        HtmlTextWriter oHtmlTextWriter = new HtmlTextWriter(oStringWriter);

        GridView gd = new GridView ();

//返回DataTable

        gd.DataSource = dataTable1;

        gd.DataBind();

        gd.RenderControl(oHtmlTextWriter);

        Response.Write(oStringWriter.ToString());

        Response.End();

    }
